BNC-2110 Installation Guide
The BNC-2110 is compatible with all E Series, S Series, and waveform
generation Multifunction DAQ devices. Some of the connectors on this
accessory may have a different function depending on the device to which
it is connected.
Table 2 describes the BNC connectors on the front panel of the BNC-2110.
Refer to the Connecting Digital/Timing I/O section for terminal block
connector descriptions.
For more detailed information about how the accessory terminals
correspond one-to-one to the Multifunction DAQ device, refer to the I/O
Connector Pinouts Table in the
E Series Help
at
ni.com/manuals
.
Connecting Analog Inputs (E Series and S Series Devices Only)
The BNC-2110 has BNC connectors for up to eight differential analog
input channels. These connectors are labeled AI <0..7>. The number of
connectors you use depends on your DAQ device and your application.
